Testing small‐scale ecological gradients and intraspecific differentiation for hundreds of kelp forest species using haplotypes from metabarcoding

Molecular Ecology, Volume 30, Issue 13, Page 3355-3373, July 2021., 2021
Abstract DNA metabarcoding has been increasingly used to detail distributions of hundreds of species. Most analyses focus on creating molecular operational taxonomic units (MOTUs) from complex mixtures of DNA sequences, but much less common is use of the sequence diversity within these MOTUs.

Population genetics of the pink snail Strombus gigas in the Yucatan Peninsula:Implications for its management and fishery

Ciencias Marinas, 2005
The genetic population structure of the pink snail Strombus gigas in the Yucatan Peninsula, Mexico, was determined by isozyme expression in polyacrylamide gels.

Shellfish subsidies along the Pacific coast of North America

Ecography, Volume 43, Issue 5, Page 668-681, May 2020., 2020
Spatial subsidies are associated with pronounced ecosystem responses, as nutrients cross ecological boundaries and cascade through food webs. While the importance of subsidies is known, the role of shellfish, specifically molluscs, as a marine subsidy has not been formally described. Focusing primarily on the Pacific coast of North America, we identify

Precarious livelihoods: Examining the intersection of fish work and ecological change in coastal Jamaica

People and Nature, Volume 2, Issue 1, Page 152-162, March 2020., 2020
Abstract Precarity has not been applied in the context of fisheries‐based work, even as working conditions in fisheries are emerging to be a real issue. There has been limited analysis of fish work outside the media spotlight or how changing ecological and biophysical conditions (e.g.

Larval Diel Vertical Migration of the Marine Gastropod Kelletia kelletii (Forbes, 1850)

Journal of Marine Sciences, Volume 2012, Issue 1, 2012., 2012
Documenting larval behavior is critical for building an understanding of larval dispersal dynamics and resultant population connectivity. Nocturnal diel vertical migration (DVM), a daily migration towards the surface of the water column at night and downward during the day, can profoundly influence dispersal outcomes.

Screening Relaxants for Efficacy and Effects on Growth for Greenlip Abalone, Haliotis laevigata Donovan

Aquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
ABSTRACT Relaxants are used in abalone aquaculture to facilitate handling, transport and grading stock, with minimal injury, stress, immune suppression and mortality. Benzocaine has been commonly used as an abalone relaxant but negative behavioural responses to exposure have been observed, and in some countries it has a withholding period, precluding ...

Reviewing the Effects of Ocean Acidification on Sexual Reproduction and Early Life History Stages of Reef‐Building Corals

Journal of Marine Sciences, Volume 2011, Issue 1, 2011., 2011
Ocean acidification (OA) is a relatively young yet rapidly developing scientific field. Assessing the potential response(s) of marine organisms to projected near‐future OA scenarios has been at the forefront of scientific research, with a focus on ecosystems (e.g., coral reefs) and processes (e.g., calcification) that are deemed particularly vulnerable.

Computer‐assisted automated synthesis. III. Synthesis of substituted N‐(carboxyalkyl) amino‐acid tert‐butyl ester derivatives

Journal of Analytical Methods in Chemistry, Volume 13, Issue 5, Page 187-197, 1991., 1991
A versatile automated synthesis apparatus, equipped with a chemical artificial intelligence, was developed to prepare and isolate a wide variety of compounds. The apparatus was to the synthesis of substituted N‐(carboxyalkyl)amino‐acids. The apparatus [1,2] is composed of units for performing various tasks,for example reagent supply, reaction ...

Conch, Cooperatives, and Conflict: Conservation and Resistance in the Banco Chinchorro Biosphere Reserve

Conservation & Society, 2014
In theory, biosphere reserves link biodiversity conservation with development, primarily through sustainable resource utilisation, and alternative, conservation-compatible economies in the buffer and transition zones outside the core area.
